I am running Centos 5.7, with Gnome interface. The Updater which automatically notifies about new updates says a tcp-wrappers update is available. When I proceed, the update fails with this error message:

Missing Dependency: tcp_wrappers is needed by package 1:nfs-utils-1.0.9-54.el5.i386 (installed)

In other words, according to the error message, I cannot install tcp_wrappers because tcp_wrappers is needed by nfs-utils. That is circular, and I need some help getting out of the trap.

I have tried for weeks, but can't find a way to get around this error, so I cannot install the tcp-wrappers update. I can install other updates if I uncheck the tcp-wrappers item, but I have discovered that some (or possibly all) of them are repeatedly offered as new updates. For example, the updater is now telling me "updated wine-gecko packages available" but I have proceeded to install those packages multiple times -- without getting error reports.

So, there is something seriously wrong with what the Gnome updater is doing. Not only is it unable to install the tcp_wrappers update because tcp_wrappers is needed, but apparently this error is affecting the proper updating of other packages.

Thanks in advance for any help.

Try
at the cmd line as root user.
Then reboot to ensure no stray yum processes are up.

Thank you for the suggestion. I had tried yum clean all before, but with no success. I tried your recipe including the reboot, but unfortunately that didn't work either.

Ok, just a shot in the dark anyway.
Can you check your repo defns, inc 'enabled' option.
Sounds like a conflict somewhere.
